Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic endoscopes, and in particular to an accessory for an endoscope and an ultrasonic endoscope. Background Art

[0002] An ultrasound endoscope is a medical device that combines endoscopy with ultrasound examination. It primarily consists of an endoscope, an ultrasound probe, and an image processing system. Its working principle is to install a miniature ultrasound probe at the front end of the endoscope. Once the endoscope is inserted into the digestive tract or other parts of the human body, the ultrasound probe can perform close-up ultrasound scanning of the digestive tract wall and surrounding organs and tissues, thereby obtaining cross-sectional images of these areas.

[0003] During the existing use process, air or fluid is injected into the patient's body through the medium pipe, or the biopsy sample collected in the body needs to be taken out through the medium pipe. Since the medium pipe itself is relatively thin and has many bends in the patient's body, the pipe is prone to blockage during use. Generally, flushing, mechanical unblocking or disassembly and cleaning are used. Flushing and unblocking are not easy to unblock when the blockage in the pipe is serious, and the blockage will re-enter the patient's body. Mechanical unblocking will cause a certain degree of damage to the inner wall of the pipe. The disassembly and cleaning method requires the endoscope to be removed from the patient's body and a new endoscope to be used for a second examination of the patient, which is likely to cause discomfort to the patient. In addition, if the blockage is not cleaned in time, it will cause corrosion or damage to the inner wall of the pipe. Summary of the Invention

Through the setting of the medium inlet pipe, the inner pipe can be extracted and replaced, which is convenient for replacement when blockage occurs in the pipe and affects subsequent operations. Convenient extraction and cleaning also avoids the situation where the medium is blocked in the pipe for a long time and causes corrosion and damage in the pipe.

[0022] In summary, the present invention overcomes the shortcomings of the existing technology. By utilizing the replaceable operation of the channels for medium introduction and extraction, another usable pipeline can be conveniently provided in the event of pipeline blockage, and the blockage can be prevented from being retained in the pipeline for a long time, causing corrosion or damage in the pipeline. The present invention has high social use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed sleeve 902 needs to be sleeved on the outside of the insertion tube 2. When the pressure plate 904 does not press on the fixed sleeve 902, the insertion tube 2 can be freely adjusted through the inside of the fixed sleeve 902. When the pressure plate 904 presses on the fixed sleeve 902, the fixed sleeve 902 can fix the position of the insertion tube 2, thereby avoiding the occurrence of deviations in the examination results due to shaking of the medical staff's hands during use.

A screw rod C1102 is threadedly mounted on the top of the front of the support frame 200. The bottom end of the screw rod C1102 is rotatably connected to the slide plate C1101. A second clamping plate 1103 that is clamped and matched with the first clamping plate 1003 is provided at the bottom of the slide plate C1101. The adjustment and coordination of the sliding mechanism B10 and the sliding mechanism C11 can be fixed to the side of the bed frame where the patient lies, so as to fix the support frame 200 as a whole, thereby ensuring the stability of the support frame 200 during use.

[0039] For other structures not described, refer to Example 1.

[0040] Working Principle: In the present invention, the sliding mechanism A8, sliding mechanism B10, and sliding mechanism C11 on the support frame 200 can be adjusted according to the height of the site where the endoscope body 100 is inserted into the patient, and then the appropriate fixed sleeve 902 is selected according to the thickness of the insertion tube 2. During the insertion stage, the pressure plate 904 can be made not to press the fixed sleeve 902, so that the insertion tube 2 can freely penetrate the interior of the fixed sleeve 902. When the predetermined inspection site is reached, the pressure plate 904 is made to press the fixed sleeve 902, thereby fixing the position of the endoscope tip 1 in the patient's body. When external gas, liquid or other media needs to be introduced into the patient's body through the medium inlet tube 6, or when external equipment needs to use the medium inlet tube 6 to absorb substances from the patient's body, the media can be transferred through the medium inlet tube 6 and the through hole 1031; When the medium inlet pipe 6 is blocked internally, the air supply structure connected to the vent pipe A505 or the vent pipe B506 is opened, allowing the gas to enter the interior of the regulating box 501 through the vent pipe A505 or the vent pipe B506, and then be discharged through the vent pipe B506 or the vent pipe A505. During the gas circulation process, the bidirectional fan blades 504 are driven to rotate, thereby allowing the main gear 503 to cooperate with the tooth groove 42 to drive the pipe sleeve 4 to rotate; Before the sleeve 4 is rotated, the push-pull rod 3112 needs to be pulled outward to allow the insert 3115 to exit from the locking hole 41, thereby releasing the rotation lock between the sleeve 4 and the inner sleeve 3. The medium inlet pipe 6 is a double-layer sleeve. The outer pipe is always connected to the sleeve 4, and the inner pipe can be unlocked and replaced. The sleeve 4 rotates in a cycle of 120 degrees. When replacing a blocked medium inlet pipe 6, the first 60 degrees can release the sealing lock between the blocked medium inlet pipe 6 and the sleeve 4, and then the medium inlet pipe 6 to be replaced is pulled out and replaced with a new one and reinserted. Then, the locking operation is performed for the last 60 degrees to seal the inner and outer pipes of the medium inlet pipe 6. In the actual operation stage, only the first 15 degrees and the last 15 degrees of the 60 degrees are used for the sealing operation between the inner and outer pipes of the medium inlet pipe 6. By utilizing the reciprocating rotation of the pipe sleeve 4 and the cooperation of the internal components of the locking tube mechanism 7, when the pipe sleeve 4 rotates forward in a unidirectional 120-degree direction, only one medium inlet pipe 6 will be affected by the locking action of the locking tube mechanism 7. When the pipe sleeve 4 rotates in the opposite direction as described above, the other medium inlet pipe 6 will be affected by the locking action of the locking tube mechanism 7. Due to the unidirectional rotation of the pawl plate 703 and the ratchet plate 7031, the two medium inlet pipes 6 will not be unlocked or locked at the same time.

[0041] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
